My girlfriend has had more sexual experiences than me, and she sometimes becomes too much extrovert in doing things, takes relationship in a faster pace and always compares and brings up the experiences she had. I always think I would never have a new experience with her that just us share and everytime I think of going someplace or having a good time extrovertly I remember her past and get depressed and dont feel like doing anything new with her thinking she might have already done it or there's nothing new for her in it.
